Mechanical Property

Packing

1. bundle packing

2. marking as per customer's requests

3. paint on the pipe as per customer request

4. pipe caps as customer request

Delivery condition

1. NBK(+N)

after cold forming, eventually above phase transition point, in a protective atmosphere of annealing oxidation medium

2. GBK(+A)

after cold forming, annealing in non oxidizing medium protective gas

3. BK(+C)

the final heat treatment after cold forming, therefore small steel pipe plastically, the plastically degree does not guarantee

4. BKW(+LC)

after final heat treatment, a tiny cold drawing deformation, continue again when machining steel pipe allowed inside certain limits cold deformation(bending, flaring)

5. BKS(+SR)

have a stress relief after cold forming, heat treatment, steel pipe can be carried out within a

certain limit in the appropriate processing.

Main products

1 Hydraulic Cylinder Tube

Used in the hydraulic cylinder of the heavy machinery, Cranes, excavator also forklifts. We can work and get the mechanical property of the clients need.

2. SRB tube

Directly used in Elevatorbuffer and Hydraulic Cylinder .This kind tube have a better inner roughness , ra0.2-0.4um and can use directly in the hydraulic cylinder tube. Length can work at most 6M.

3. Cold finished tube

Widely Used. Processing range 30-300mm, biggest length is 11M.
